Amos Nachoum is one of the greatest underwater photographers of all time: he already caught dangerous animals such as anacondas, leopard seals, white sharks, killer whales and crocodiles with his lens. The photographer always approaches the animals without protection. At the age of 65, Nachoum faces his last major challenge: he wants to swim with a polar bear without any barriers. The film accompanies him on his journey to the high arctic of Canada, which also awakens painful memories for the underwater photographer.
